@Robert K: Thank you for answering my question and providing the reference to Power Tips 54 & 55. Practically, that inductor part would have some small amount of parasitic series resistance. Won't that help in damping the second stage resonance? I understand why the resistance might be required in the circuit for SPICE simulation.

What are those 0.5 ohm resistors R1 and R5 for? Are those necessary? Also I see that you have a 150 ohm resistor at the 3.3V output. Is that necessary to provide a minimum load? I find this tip very useful and would like to try experimenting. Thanks!

In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
